COLOFULWAY 5/8 Inch OD 304 Stainless Steel Roller Shaft (5/8-13-1/4)
Features: Includes 1 shaft (5/8″ x 13-1/4″), 4 pal nuts (two for use, two for replacement). Made from 304 stainless steel to resist saltwater corrosion and abrasion. Installation is straightforward—tap the cap nuts on with ease; a hammer is recommended for solid seating.
Best for: boaters needing corrosion resistance in saltwater environments and a complete hardware kit for immediate installation. Better for: larger or heavier trailers that require longer shaft length for stable roller mounting. Caution: verify compatibility with your roller brackets and nut sizes before installing.
Attwood 11285-3 Roller Shaft Set
Includes a 5/8″ shaft and a 12″ roller system configuration, suitable for standard trailer setups. Best for: general boating trailers that require a reliable, mid-length shaft with compatible hardware. Better for: users who want a complete set with nuts included for fast replacement. Caution: shaft length should match your roller bracket width for optimal fit.
Attwood 11283-3 Roller Shaft Set
Features a 9 1/4″ long shaft with matching pal nuts in a solid zinc-plated steel build. Best for: boats and trailers where extra shaft length is needed for a stable roller alignment. Better for: replacements on older trailers that use standard 9 1/4″ shafts. Caution: zinc plating reduces direct corrosion risk but still requires regular inspection in harsh environments.
COLOFULWAY 5/8 Inch OD Stainless Shaft (5/8-11-1/4)
Same build as the 13.25″ variant but sized at 11 1/4″ length. Best for: compact trailer brackets and shorter loading ramps. Better for: setups where a shorter shaft reduces clearance issues. Caution: ensure compatibility with your roller assemblies’ length and mounting holes.

Buying Guide: Key Considerations for Boat Trailer Roller Shafts
- Material and corrosion resistance: Stainless steel shafts offer superior corrosion resistance in saltwater environments, while zinc-plated steel provides budget-friendly protection.
- Shaft length and fit: Measure your trailer bracket width and roller length to ensure the shaft will pass through and align the roller properly.
- Pal nuts and installation hardware: Check if the set includes pal nuts and cap nuts, which affect installation ease and replacement options.
- Compatibility with rollers: Confirm that the shaft diameter, thread type, and overall length align with your current roller system.
- Intended use: For heavy loads or frequent launches, prioritize longer shafts and robust materials; for light-use trailers, standard-length shafts may suffice.
- Maintenance: Stainless shafts resist saltwater corrosion but still require periodic inspection for wear, particularly at cap nut seating points.
Frequently Asked Questions
- What shaft diameter is most common for boat trailers?
Typically 5/8 inch is a standard diameter for many trailer roller shafts, but always verify your roller’s hole size. - Do all shafts include pal nuts?
No, some sets include pal nuts while others require separate purchase; verify the product listing. - Which material lasts longest in saltwater?
304 stainless steel offers strong corrosion resistance; zinc-plated steel is adequate for non-saltwater use or short-term exposure. - Can I replace just the shaft or should I replace the entire roller assembly?
Many buyers replace just the shaft and nuts if the roller and brackets are sound; ensure compatibility to avoid misalignment. - How do I install a new boat trailer roller shaft?
Slide the shaft through the roller and bracket, insert pal nuts, and tighten. A light hammer may help seat nuts securely. - Is length important for boat trailers with 10-inch rollers?
Yes, use a shaft length that matches your roller bracket spacing to ensure smooth loading and unloading.
